Mateta had been a long-time target for United, who are keen to bolster their squad with a new striker this summer, report Mail Sport. The Frenchman is inclined to stay at Palace, though, as they prepare for their first-ever European campaign.
United have also been offered PSG forward Goncalo Ramos. The 23-year-old fits the age profile the club are after and the report states it could be a deal worth keeping an eye on as the summer progresses.
